I agree with others. It looks like the latest touch has at least the potential to become a gadget I'd want to buy:
1. WiFi N. Why? Speed isn't the issue. Because at home I could make my network N-only and make security a bit tighter. I'd also be ready when b/g becomes rarer.
2. FM transmit. Like others, I don't want to klutz with some external gadget to play through speakers. If the chip can do it, why not do it?
3. FM receive. Less a big deal, but not a bad idea.
5. Microphone. For VoIP and voice notes on the go. Without it, even a used 1-G iPhone makes more sense.
6. A decent camera with still and video photography. Again, handy for notes on the go and times when I didn't know I needed a camera. If space is an issue, make the touch thicker and put a bigger battery in most of that space. No one complains about the iPhone being too thick, they won't mind a less thin touch, particularly with double the battery life.
As it stands now, buying the new touch makes little sense. I can get the same features in a used touch for less and more features in a used 1-g iPhone, also for less. That's particularly true of the low-end touch, which ships without the remote earphones with mike. That makes it's real price $230.
Apple should quit being so secretive. If the current models are merely interim to fill in until the real 3-G touches come along, they should say so and give us dates.
